Product Description

Built with the bowhunter in mind, the new RX-FullDraw 4 gives you the advantage you need to tag out every season. And with ½ yard accuracy, there's no second-guessing your distances. The RX-FullDraw 4 rangefinder features our unique Archer's Advantage software, which uses your arrow weight, arrow velocity, and peep height to calculate extremely accurate ballistic solutions out to 175 yards. It is also loaded with Flightpath™ technology, taking the guess work out of achieving the perfect shot every time. This extremely fast rangefinder also ranges out to 1,200 yards, so even if you're too far to take the shot, you'll know how much distance you need to close in order to seal the deal.

Just buy it
It’s a great upgrade from my old range Finder. It’s smaller, much more clear through the lens, and it’s fast. My old range Finder was questionable at 60 yards and often wouldn’t give me a range at all. This one is fast and has yet to give me a range.

Getting it set up took me a minute with a few items I never cared about like how fast my was arrows were flying

Worked great until the red display numbers disappeared. Called customer service and they would only give me a discount on purchasing a new rangefinder. Very disappointed with the life of the unit for the price paid. Purchased new rangefinder from another company.

Genius product
I set up my rx4 with my arrow weight, velocity, peep to shaft distance and have been really impressed with the performance of this range finder. I shot the total archery challenge this year with the rx4 and it was the perfect place to put the flight path technology to the test. Great range finder.

Great rangefinder
I use this rangefinder primarily for marked yardage 3D competitions. I am sure it will see time in the hunting woods. Also hoping to use it at extreme 3D events.

Best rangefinder for bow hunting
After receiving this a couple of weeks ago, I’ve played around with the operation. Used in the middle of the day as well as the middle of the night. I’ve used it inside with all the lights off and blasted into a bright light. I even left in vehicle to see if temperature affected it... There was no change of operation. I had to change batteries on trail cams, so I took it along and dropped it into the snow (wish I could say it was on purpose and that I was testing the unit, lol) still worked with no issues. All I can say is wow! Real simple conclusion is that it works. And it works well. It does everything I need it to do and I haven’t even set up the “Archers Advantage” yet (haven’t got all the info off my new bow yet since I’m waiting on a set of new GAS Ghost XV strings). The display is clear and locks on to everything immediately. Snow, tree, brush pile, my dog, doesn’t seem to matter, it locks on. Absolutely worth the money I spent. I highly recommend and am looking forward to see operation once I get “Archers Advantage” working.
